Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for receiving and blowing gaseous and/or fluid components into at least two separate partial vessels provided with discharge valves; It relates to a pressure vessel having a vessel body or frame provided with a bottom and a hopper on the end face for mixing the components mentioned above when discharged by a foaming medium.

Apart from the known pressure vessels for the discharge of only one fluid phase, as described for example in U.S. Pat. Pressure contained and mixed immediately before processing by forming a connection between the separate stored components, such that the discharge takes place as a mixture through a single distribution valve. Containers are also known (POT Wo 84
101355). One drawback of this structure is that, on the one hand,
Homogeneous mixing of the ingredients is not ensured and, on the other hand,
The mixing that takes place in the container may occur if the contents of the container are not completely processed immediately after the mixing of the ingredients.
It is about change.

In other pressure vessel types, the aforementioned disadvantages are overcome by placing the components in separate partial vessels and mixing only the partial amounts of the components needed for dispensing purposes. However, at that time, other problems arise. In particular, through the process of emptying, the component is -
It should be mixed with a constant mixing ratio, which means that the compressive load or the compressive load on the individual partial vessels remains unchanged, i.e. during the process of emptying the pressure vessel. It is assumed that the change in the shape and position of does not result in any change in the mixing ratio. It is also necessary that the discharge valves of the individual partial vessels be located in the hopper, but preferably standard valves can be used. However, this cannot in practice be used with the commonly used convex hoppers. In this regard, please refer to the applicant's specification regarding the structure of a comparable hopper dated the same date (
BE 21180).

The problem that the present invention seeks to solve is to provide a pressure vessel of the type mentioned above, which can be exposed to the action of high pressures for a given mixing ratio, in order to seal the partial vessels. A standard discharge valve is used and the arrangement consists in that the mixing ratio of the components is adapted in a simple manner to the required ratio value.

According to the present invention, this problem is solved when the hopper has at least two
constructed as a wall consisting of a number of superimposed and joined partial hoppers, in which openings corresponding to the number of partial containers are provided for receiving outlets cooperating with the partial containers; is solved by being connected to the adapter head for actuation of the outlet and for setting the mixing ratio of the components.

Suitably, the hoppers are configured, for example, as partially contoured, but substantially disc-shaped walls, of which the inner part hopper cooperates with the inner part hopper. It has a smaller diameter than the external part hopper. Due to the double wall, adequate hopper strength is obtained even without the convex hopper shape and, moreover, the outer part hopper of larger diameter projects beyond the inner part hopper. The rim facilitates flanging the hopper to the rim of the body.

The invention will now be described in detail with reference to the accompanying drawings, with reference to an embodiment having two partial containers and several different accessories.

The pressure vessel 1 shown in FIG. and an inwardly curved bottom portion 3;
It consists of hopper 4. The pressure vessel 1 accommodates two partial vessels 5.6.
6 is made from plastic and its bottom 7.8
is supported on the piston 9.

The piston 9 is acted upon by a gas propellant filling, which fills the space between the piston 9 and the bottom 3, and a seal 10, for example a press-fit plug,
Alternatively, it can be filled via a one-way valve. The hopper 4 has two circular openings 11, 12 (
(see FIG. 2), its structure will be explained below with reference to FIGS. 3 and 4.

As can be seen in FIGS. 3 and 4, the hopper 4 comprises two partial hoppers, namely, on the one hand, an internal partial hopper 13;
On the other hand, it consists of an external partial hopper 14. The diameter of the inner part hopper 13 corresponds approximately to the inner diameter of the cylindrical container body 2 and has a greater wall thickness than the outer part hopper 14. The outer part hopper 14 has a larger diameter than the inner part hopper 14,
It has a groove 15 in the circumferential area ftJt, and the inner part hopper 13 leans against the groove 15 and engages from the inside.

The external part hopper 14 is provided with a flange part 16 on its periphery, by means of which a flange joint between the container body 2 and the hopper 4 is created. Only one partial hopper, namely in the present example external partial hopper 1
Due to the fact that only 4 is used for said flange joint, this flange joint can be performed with limited outlay and in a reliable manner.

As can be seen in FIGS. 3 and 4, the opening 11.12 is provided with a rim 17, which rim 17 is approximately at right angles to the plane of the hopper 4 and which also has an inner part hopper 13.
away from Rim 17 connects both partial hoppers 13.
14 so that its wall thickness represents the sum of the wall thicknesses of the two partial hoppers 13.14 and does not require any additional flanged joints or welding. .

The rim 17 serves to receive the valve plate 18, the curvature 21 of its edge surrounding the unrounded rim 17 formed from the partial hopper 13.14 and being shirred therewith. . In this way, a reliable connection is created between the valve plate 18 and the hopper 4.

The partial container 5.6 is gusseted and configured as a bag.
It has upwardly open socket-shaped necks 22, 23, which have reinforcing beads 24 (see Figures 3 and 4). The edges of the neck 22, 23 are placed under the bend 21 of the valve plate 18 on the rim 17 of the hopper 4, and then an overhang is made with the valve plate 18. In this way, the bag neck 22 , 23 forms a reliable seal between the hopper 4 and the valve plate 18 . Each valve plate 18 has a valve 19
．． 20, but this valve allows each partial container 5
．． A perfect seal of 6 is ensured. Valve plate 18 and valve 19
．． 20 are standard parts, which can be used without any modification to the construction of the hopper 4.

The valve 19 , 20 consists of a tubular valve tappet 25 and an elastically deformable valve body 26 that is engaged in an opening 27 in the bottom 28 of the valve plate 18 . The structure and function of valve 19.20 is described, for example, in U.S. Pat. No. 3.662.92.
It has been publicly known since No. 6.

The essentially planar hopper 4 contains the partial containers 5.
6, two or more valves 19 as a function of the number of valves 19
．． 20. Partial hopper 13
．． 14, the hopper 4 becomes a partial hopper 13.1
A wall thickness of 4.4 can even be used for high pressures without having to be made too thick. Partial hoppers 13.14 form stable entities. This is because the partial hoppers 13, 14 are suitably interconnected, for example by spot welding or gluing. As can be seen in Figure 4, two partial hoppers 13.1
4, a recess 29 is formed in which a passage 30, 31 is provided. This recess 29 can also be configured as an evacuation means by inserting an elastic tongue 32 into the recess 29 (see FIGS. 5 and 6). The tongue 32 engages the passage 31 of the outer part hopper 14 and is therefore in a closed position, in which the interior of the pressure vessel 1 is sealed against pressure leaks. If the tongue 32 is moved away from the passage 31 by pressing the pin 33 and brought into the open position (see FIG. 6), the interior of the pressure vessel 1 and the external air A connection is formed between. This evacuation operation is necessary whenever the component is removed from the partial container 5.6, so that the piston 9 under the action of the propellant gas charge can empty the partial container 5.6. to be able to carry out its upward movement.

When using the pressure vessel I, the components must be brought together and mixed before discharge from the partial vessel 5.6; an adapter head 40 is provided to bring the components together. This head 40 is connected to the partial container 4.
．． 5 is mounted on the valve 19.20, and
It has two supply lines 41, 42 which enter into the connecting member 43. Screwed into the connecting member 43 is a mixing tube, not shown, in which the components are mixed and brought to the processing point.

The adapter head 40 is configured in a multi-part shape,
It is composed of a main body 44 and a head 45 having a connecting member 43. The head 45 is screwed onto the body 44 by means of a box nut 46, which body 44 also has a stop plate 49.

In order to seal the adapter head 40 over the valve 19.20, a relatively soft, conical sealing sleeve 47 is inserted into the body 44 for each supply line 41.42. In each case, at the transition between the body 44 and the head 45, a distribution sleeve 48 connects the supply line 41.
．． It is installed in 42. The distribution sleeve 48 makes it possible to set the mixing ratio of the components, thereby
After removing the head 45, the sleeve 48 is made replaceable.

The piston 9 consists of two parts, namely:
These two parts, on the one hand a sealing part 50 and on the other hand a tip-shaped piston part 51 (see FIGS. 10 and 11), are made of plastic and are connected to each other, for example by gluing or welding. On the side of the 0-portion container to be covered, the sealing part 50 has a recess 52 into which the bottom 28 of the partial container 5.6 protrudes and is also supported by ribs 53 ( Chapter 10.11
In the center of the recess 52 a projection 54 is provided, behind which a projection 56 of the head 57 of the piston part 51 projects and is centered. The center of the pond in the piston portion 51 is determined by the depression 5.
This is achieved by a rib 58 bounding a recess 59 facing 2. The two recesses 52, 59 are surrounded by a cylindrical wall 60, which has a number of circular grooves 61 for receiving packing rings 62. In FIG. 10, there are three packing rings 62, however, the number can be changed arbitrarily.

According to FIG. 11, the piston section 51 is a relatively thin plastic section whose piston skirt 63 is
A conical seal and guide lip 64 is provided on its free edge.

To remove components from the partial container 5.6, the adapter head 40 is pressed, which causes the valve 19.20 to
To be opened simultaneously and uniformly. Depending on the pressure exerted uniformly on the bottom 28 of the partial container 5.6 by the piston 9, the components are fed into the connecting member 43, and the distribution sleeve 48 allows the ratio of the components to be constant. becomes.

The ratio of the components to be discharged can also be obtained by means of partial containers 5.6 with different cross sections. As can be seen from the two dashed lines in FIG. 2, the partial containers 5.6 have the same cross section. The distribution sleeve 48 allows the ratio of the components to be varied to a certain extent. However, if the mixing ratio is large, partial containers 5.
6 must have different cross sections. For example, one cross section may be circular and the other may be kidney-shaped. These possibilities can be varied within wide limits and can be adapted to the viscosity of the components.

Actuation means 85,86 shown in Figures 8 and 9 are used to press the adapter head 40 during evacuation of the components. Both actuating means 85,86 are connected to the fixing sleeve 87
This sleeve 87 engages with the flange of the hopper 4. As can be seen in FIG. 8, a bending lever 88 is pivotably mounted on the fixed sleeve 87 at the end of one lever arm 89. The other lever arm 90 extends along the pressure vessel 1 and is used for manually actuating the bending lever 88.

Via the pressure of the bending lever 88, the adapter head 40 is pressed, thereby causing the valve 19.20 to open. On the side of the hopper 4, two pins 33 are fixed to the stop plate 49 of the adapter head 40 (see Figures 5 and 6), and when the adapter head 40 is pressed, the tongue 3

The adapter head 40 is not shown in Figures 8 and 9; instead, only the single G, its hopper, or stop plate 49 is shown for purposes of illumination. It is.

According to FIG. 9, the actuating means 86 has a pivoting sleeve 93, which is screwed onto the fixed sleeve 87. A control ring 94 is also provided on the pivoting sleeve 93;

The pressure vessel 1 described above can be used for any component. Not only two, but also three or even more components can be accommodated in the pressure vessel 1, the hopper surface allowing the arrangement of valves with the help of standardized valve plates. shall be. The strength of the hopper 4 is determined by the partial hopper 13.
Through a selection of 14 wall thicknesses, it can be adapted to specific site requirements. The partial hoppers 13,14 can suitably be made from different materials, but for example:
It is also possible for the container wood and the container bottom 3 to be made from different materials. Suitable materials are, for example, tin plate, aluminum, its alloys, plastics with or without reinforcement, or metal-plastic composites. The parts of the adapter 40 are preferably made of plastic or metal and have one actuating means 85.86.
is made of plastic or metal. On top of that,
By means of distribution sleeves 48 and partial containers 5.6 of different dimensions, it is also possible to adapt the distribution ratio within wide limits.

It is also possible to operate the pressure vessel 1 without the piston 9. In this case, passages 30 and 31 in hopper 4 are
Alternatively, the tongue 32 may be left in the open position.

Since the present invention has the above-described structure and operation, it can be exposed to high pressure while maintaining a constant mixing ratio, and the seal of the partial container can be It has the advantage of being able to provide a pressure vessel in which standard valves can be used for the purpose and the mixing ratio of the components can be easily adjusted to the desired ratio. It is something that can be done.
